There are 25 prime numbers under 100.
So there are (25 x 24 x 23) = 13,800 products of three of them at a time.
Clearly, we're not about to sit here and list them all, mainly because anybody
who needs them surely knows how to generate them for himself.
Here are five of them:
The smallest one is (2 x 3 x 5) = 30
2 x 5 x 7 = 70
3 x 5 x 7 = 105
3 x 7 x 11 = 231
The largest one is (83 x 89 x 97) = 716,539
It's more likely the person wants to know about three different prime numbers whose products are less than 100. Those would be 30, 42, 66, 70 and 78.
All the numbers less than 100 that are the product of exactly three different prime numbers are 30, 42, 66, 70, and 78.
Since there are infinitely many primes, there are infinitely many numbers that are products of 3 primes.
Yes.
All the numbers less than 100 that are the product of exactly three different prime numbers are 30, 42, 66, 70, and 78.

Since there are infinitely many prime numbers there are infinitely many sets of three prime numbers and so there are infinitely many products.
All the numbers less than 100 that are the product of exactly three different prime numbers are 30, 42, 66, 70, and 78.
Since there are infinitely many primes, there are infinitely many numbers that are products of 3 primes.
Yes.
no
Two and three.
No.
30 is the product of three different prime numbers.
Numbers that have 2 factors are prime numbers; Numbers that have 4 factors are either: * the cube of a prime; or * the product of two different primes; Numbers that have 8 factors are either: * a prime to the power 7; * the product of a prime cubed and different prime; * the product of three different primes.
15 is the product of two prime numbers; 3 x 5
